Dear doctor, I am 63 years old, female, I went to the provincial hospital and the results were myocardial ischemia, sinus bradycardia, coronary insufficiency. Always having chest pain, sometimes screwing up the neck, making it difficult to breathe.

Acute coronary syndrome (ACS) is a term used to describe a range of conditions involving a sudden reduction in blood flow to the heart. ACS typically causes severe chest pain or discomfort. It is a medical emergency that requires prompt diagnosis and care.
